actually the AA is a myth.... bro-logid spread it across forums and even sellers.
onyl typoe thats been used in research is WATERLESS AA, and that would hurt and not be used by humans... show me even ONE research paper that used AA... you wont... and iv talked to chemists about this. if gone blue in the face trying to explain it to people that its bs.

Glacial acetic acid is a trivial name for water-free (anhydrous) acetic acid. Similar to the German name Eisessig (ice-vinegar), the name comes from the ice-like crystals that form slightly below room temperature at 16.6 °C (61.9 °F) (the presence of 0.1% water lowers its melting point by 0.2 °C).[SUP][11][/SUP]
A common abbreviation for acetic acid is AcOH, where Ac stands for the acetyl group CH[SUB]3[/SUB]−C(=O)−. Acetate (CH[SUB]3[/SUB]COO[SUP]–[/SUP]) is abbreviated AcO[SUP]–[/SUP]. The Ac is not to be confused with the abbreviation for the chemical element actinium.[SUP][12][/SUP] To better reflect its structure, acetic acid is often written as CH[SUB]3[/SUB]–C(O)OH, CH[SUB]3[/SUB]–C(=O)OH, CH[SUB]3[/SUB]COOH, and CH[SUB]3[/SUB]CO[SUB]2[/SUB]H. In the context of acid-base reactions, the abbreviation HAc is sometimes used,[SUP][13][/SUP] where Ac instead stands for acetate. Acetate is the ion resulting from loss of H[SUP]+[/SUP] from acetic acid. The name acetate can also refer to a salt containing this anion, or an ester of acetic acid.[SUP][14][/SUP]

and only used cuzz they had it on hand^ and not point of research.
I agree with you about the rest.... mix as you use it, trying to "make it last longer" once mixed is a bit dumb.. its gonna degrade.. use it all in one run... and one bottle... dont expect much anyway.
also water expands when you freeze it... this may also damage the peptide...
